Abstract:According to the safe firing range management requirements of weather modification operation, an analysis is made of the factors influencing the safe firing range of weather modification operation，including equipment performance, ammunition stability, high altitude airflow, site elevation and personnel operation level, etc. This paper puts forward a method for drawing the safe firing range map of weather modification operation, and the specific steps are as follows: (1) the information interpolation processing of the ejection data tables; (2) the artificial identification of the sensitive area of the ground safe operation; (3) the inverse calculation of projectile impact points corresponding to initial firing data; (4) the error correction design of different influence factors; (5) the fusion processing of geographic information data; (6) the output of the safety shooting range map. This paper also designs the system for drawing safety shooting range maps based on the artificial identification technology of highresolution satellite image data and digital elevation model data (DEM data). Practical application shows that the safe firing range map outputted by the system can solve the problems of incomplete safetymarking elements, low resolution, and low level in information in the traditional maps, has practical value for improving the operational efficiency and safety management level, and can be popularized to all levels of weather modification operations.
